[Mono-dev] System.NullReferenceException, what does it mean?

There's not much anyone can do with that trace, especially as we don't
have the source. If you compile with debug symbols (mcs -debug) and
run with debugging support (mono --debug) you'll get line numbers, and
will be able to find out what operation is causing that exception.
